Application filed. October 26, 1912. Serial No. 727,836.

To all whom it may concern:

Be it known that I, JOHN A. JONES, a citizen of the United States ofAmerica, and resident of Cincinnati, county of Hamilton, and State ofOhio, have invented certain new and useful Improvements in MetallicWindow-Sashes, of which the following is a specification.

This invention relates to metallic frames, such for example as windowsashes, and-particularly to frames which are formed of separateintersecting members.

shows a tongue, which forms a detail of my 1 invention, in the positionit occupies during the'operation of assembling the members. Fig. 4 is afragmental perspective view of a slotted member on which a tongue isformed and which forms a detail of my invention. Fig. 5 is a fragmentalperspective view of a notched member which cooperates with the slottedmembershown in Fig. 4. Fig. 6 is a fragmental perspective view of themembers shown in Figs. 4 and 5 in positions they occupy during theassembling operation, prior to securing them'toge'ther, Figs. 6, 3, and2, respectively, illustrate three successive steps in the operation ofassembling and securing two intersecting members to- I gether inaccordance with my invention.

In carrying out my invention I provide a slot in one member throughwhich the cooperating intersecting member is inserted and in which it islocked by means of a .i tongue which projects partially across the slot.

In the drawings I have shown my invention as applied to T-bars, but Ideslre it to be understood that the invention may be ema ployed," withequal success with channel irons, angle irons or other standard sectionsand that I do not limit myself to sections of any form or shape.

As illustrated, the web 8 of one member, which for convenience ofdescription I will term the vertical member 9, is provided with a slot11 and a tongue 12, which, as shown, is struckfrom the metal of the weband is so formed that it projects partially across the slot 11, but iscapable of being bent at an angle to the web 8 for the purpose ofuncovefing or clearing the passage through the s 0t.

The cooperating member, which for convenience of description I will termthe horizontal member 13, is adapted to project through the slot 11,inthe member 9, and is notched at 1 1 and 15, as illustrated in Fig. 5.The notch 14 is formed in the edge of the web portion 16 of the member13, for the purpose of engaging an edge of the slot 11 in the member 9,when the members are assembled in their normal positions, and it issubstantially of the same width as the web 8. The notch 15 is formed inthe head portion of the member 18, extends to the inner edge of the web16, and is adapted to receive the head portion of the-member 9, when themember 13 is in the normal position with relation to the member-9.

The slot 11 is so formed that it is capable of permitting the horizontalmember to be passed through it when the tongue 12 is moved to theunusual position; that is, when the tongue 12 is bent at right angles tothe web 8. In the illustrated embodiment this is accomplished by soforming the slot 11 that it extendslongitudinally'of the web 8 and isprovided with an off-set 17, which extends from the slot inwardly-to thehead portion of the member 9, and produces a substantially L-shaped slotin the web, one portion 11 of which is wide and extends longitudinallvof the web and the other portion 17 of which is narrow and'extendstransversely of the web. The Off-set l'? is substantially the same widthas the thickness of the web 16, of the member 13, and the corner orshoulder formed between it and the slot 11 is rounded for a purposewhich will hereinafter be described- The length of the slot 11 is alittle greater than the combined width of the web 16 and the thicknessofsthe headportionof the member 13. The

; of the member 8.

tongue 12 is so formed that it extends longitudinally of the slot 11,when it is in the normal position, and it is of such length .that.thedistance between its free end and theopposite edge 18 of the slot 11, issubstantially equal to the thickness of the web of the horizontalmember. r

The operation of assembling the horizontal and Vertical members is asfollows: The tongue 12 is bent to a position substantially at rightangles to the web 8, the horizontal notch 15 is located directlyopposite to the head portion of the member 9. The member 13 is thenturned or tilted so that its web is moved to a position at right anglesto the head portion of the member 9 and into contact Withv the edge 18of the slot 11. In turn- .ing the member 13 to this position the inneror severed edge of its web 16 moves intothe off-set 17 of the slot 11,its notch 14 moves into engagement with the upper edge of the slot 11,and the edges of its notch 15 engage the edges of the head portion ofthe member 9. The shoulder formed between the slot 11 and the off-set isrounded for the purpose of aiding in tilting themember 13 to its normalposition, and the severed edge of the web 16 of the member 13 may alsobe notched or rounded for the purpose of causingthe web to more easilyenter the ofi-set 17 After them'ember 13 is in the position illustratedin Fig. 3, the tongue 12 is bent inwardly .or back to its normalposition, so that its lateral faces are flush with the faces o-fthe web8, and so that its free end engages the adjacent face of the web portion4 16' of the member 13. This positively locks the members 9 and 13together, since the tongue 12 prevents the member 13 from beingtilted'in the slot '11 and the notches 14 and'15-positively engage themember 9 and it cannotbe releasedtherefrom except by tilting the member13. 1 I

It will be understood'that the olf-set 17 of the slot 11 may bedispensed with by providing a notch in the severed or inner edge of theweb 160i the member 13, as shown ber 13, will rest upon the'head portionof the member 8 instead" of being notched out,

as illustrated. Such a construction reduces the width of the notch 14,shown in Figs. 5 and 6 to the width of the web 8 of the member 9. Whenthis construction is employed the notch 13 must be increased in depth toaccommodate the tilting operation, since the member 13 will turn aboutthe edge of one of the flanges of its head portion during the tiltingoperation, instead of turning about the inner or severed edge of its webportion 16.

In forming a window sash or frame portion, with the members illustrated,each horizontal member 13 is provided with as many sets of notches 14and 15 as there are vertical members 9 in the frame or sash; and each"ertical member is provided with as many slots 11 and cooperatingtongues 12 as there are horizontal members in the frame or sash. Thevertical members are then located in parallel relation to each other andthe horizontal members are tilted relatively to the vertical members, asshown in Fig. 6 and are inserted through the slots 11 to such positionsthat each set of notches 14 and 15 is located opposite to a verticalmember. Each horizontal member is then turned, relatively to thevertical members, to the position shown in Fig. 3 and the tongues 12 arethen bent inwardly so that their inner edges engage the webs 16 of thehorizontal members, as shown in Figs. 1 and 2. This locks the memberstogether and forms a permanent frame or sash. By properly proportioningthe width of the notches 14 and 15 to the webs and headportions of themember 9, and by properly proportioning the length of the tongues 12, sothat they firmly press the webs, engaged by them, into contact with theedges 18 of the slots 11, the joints between the horizontal and verticalmembers will be absolutely rigid and there will be no relative motionbetween the members.

While I have illustrated my invention in connection with a metal frameor window sash, I desire it to be understood that my invention may beemployed in looking any two intersecting metal members together and thatvarious changes, substitutions, omissions, additions and variations maybe made in the apparatus illustrated without departing from the spiritand scope of my invention as set forth in the appended claims.

What I claim is:

1. In an interlocking joint for bars, a bar having an L-shaped eyetherein, a single tongue formed from the material removed from saidL-shaped eye, a second bar having a width substantially equal to thelength of the eye of the first bar, said second bar having oppositelydisposed notches leaving an, unnotched portion of the bar intermediateits marginal notches, substantially equal,

to the width of the offset portion of the L-' shaped eye of the firstbar through which the second bar is adapted to be thrust and interlockedtherewith by a partial rotation, in which position it is secured by thereturn of the single tongue to the plane of the web.

2. In an interlocking joint for bars, a flanged bar having an L-shapedopening confined to the web portion thereof, a second bar havingoppositely disposed marginal notches extended through the opening of thefirst bar and engaged therewith by a partial rotation, the second barbeing seated against the terminal wall of the oliset portion of theL-shaped opening, and means for locking the bar in its adjustedposition.

3. In an interlocking joint for bars, a

flanged bar having a longitudinally disposed substantially L-shapedopening confined to the web portion thereof, a second bar havingoppositely disposed marginal notches extending through the opening ofthe first bar and interengaged in the offset portion thereof by apartial rotation, said second bar extending in opposite directionsbeyond the transverse limits of the offset portion of the opening, andmeans for retaining the bar in position.

In testimony whereof, I have hereunto subscribed my name this 24th dayof October, 1912.
